I have checked the game files and would like to share what I have found.

There is a BASE.PCK under StreamingAssets that contains files from the original game, including MIS and GSC scripts and Y64 map images.
Character animations (ABI), scene models (MBI) and sound files are missing, which are located in Unity asset bundles in StreamingAssets\aa\Windows\StandaloneWindows64 and in Unity formats (Unity textures, models and sound files). I have seen images from the big map, so I think Y64 may not be used any more.

Wrong place to ask technical support, @dukepapas. Use the Steam bugreport forums for communicating such issues with the publisher>developer. Usually you need the latest graphic drivers, Unity can be true asshat Again, try to ask on the Steam forums: https://steamcommuni...10/discussions/
